What type of clouds are known to form and grow through the process of convection?

• Cumulus clouds

• Cumulonimbus clouds

• Cirrus clouds

• Altostratus clouds

What is a significant hazard posed by cumulonimbus clouds to both manned and unmanned aircraft?

• High winds

• Large hailstones

• Damaging lightning

• All of the above

Standing lenticular altocumulus clouds are formed:

• Through the process of evaporation

• On the crests of waves created by barriers in wind flow

• By condensation at high altitudes

• Near the ocean surface

What is a characteristic of standing lenticular altocumulus clouds?

• Rapid movement

• Ragged edges

• Smooth, polished edges

• Formation at ground level

Why should standing lenticular altocumulus clouds be avoided by unmanned aircraft operators?

• They indicate strong turbulence

• They indicate clear skies

• They enhance visibility

• They are harmless

What is a frontal zone?

• A zone with no air masses

• A zone where temperature and humidity remain constant

• A zone between two different air masses with rapidly changing conditions

• A zone where only warm air masses are present

What poses a serious threat to flight safety due to its effects on an aircraft's lift and drag?

• Lightning

• Hail

• Ice formation

• Rain

At what temperature does aerodynamic cooling lower the temperature of an airfoil to, leading to ice formation?

• Below -10°C

• 0°C

• 10°C

• Above 20°C

How many stages are there in the lifecycle of a thunderstorm?

• One

• Two

• Three

• Four

Which stage of a thunderstorm poses the most risk to unmanned operations in the field?

• Cumulus stage

• Mature stage

• Dissipating stage

• None of the stages pose a risk
